Applicationfiled July 12, 1922. Serial No. 574,357;

cool, without the use of ice, the device being of the general type known as a safe.

A further object is to effect the result desired by the use of a casing provided with inner walls of textile material ant particular means for keeping these walls moist, so that the air circulating through the outer perforated walls will constantly evaporate the water absorbed and conducted by the textile material.

A still further object is to providea' casing adapted to contain suitable shelving and having a water tank located in the upper portion, a trough located near the bottom, and inner walls, or curtains, extending from the tank to the trough, and designed to be mositened by the water from the tank, the evaporation cooling the articles within the casing, or safe, and the trough retaining a suflicient quantity of water to protect the food from ants or the like.

51th the foregoing and other objects in View, the invention consists in the novel construction and arrangement of elements described and claimed, it being understood that modifications may be made withinthe scope of the claims without departing from the spirit of the invention.

In the drawings, Figure 1 is a view of the device in front elevation; Figure 2 is a side elevation; Figure 3 is a rear elevation; Figure 4 is a vertical section; Figure 5 is a horizontal section on the line 5-5 of Figure 1; Figure 6 is a perspective view of the upper tank, from which the textile walls or curtains receive mositure.

The casing includes an upper portion 10,

a lower portion 11, and structural corner elements, such as 12. The shelves. 13 are carried by the transverse elements 14:, and it is the intention that there shall be a space between the series of shelves and the inner and outer walls of the complete de vice.

The doors 15 and 16 may be of usual construction, and wire netting, or other equivalent material, is stretched over the openings of the doors, and about the other three sides of the safe.

Inner walls, or curtains 20, of textile material, extend from the top to the bottom and are located on at least three sides of the device.- The curtains are intended to be free of the shelving and the outer walls of netting.

An upper tank 22 located in the portion 10 of the casing, contains a sufiicient quantity of water, and the sides are provided with outwardly extending flanges 23 acting to space the curtains from the walls of the tank. Suitable engaging or attaching devices 24 are carried by the elements of the.

tank and permit the curtains to be suitably secured, there upper portions being immersed in the water.

The base on which the device is mounted the molding 27 of the casing projecting outwardly with reference to the base, in the includes an upper element 25, and legs 26, 7

walls extend into the trough, and may be secured, if desired, by means of engaging devices 29. The trough is provided with an overflow device 30, and it is designed that the water connected by the textile material shall pass into the trough, a small quantity collecting there, and any excess being discharged by the overflow device. The textile walls will be kept sufliciently moist to permit of constant evaporation, the air passing through the outer wall of wire netting or the like. The water collecting in the trough 28 will serve to protect the food in the safe, from ants, or the like, and the base including the trough may be used when desired for mounting a small refrigerator or ice box, the same protection from insects being afiorded The trough 28 is shown in Figure 5 as being shaped like a rectangular frame ineluding enlarged cornerportions 32 which surround the legs 26, an inner upwardly projecting sleeve or the like 33 being of a size to fit the legs, and permitting of the construction of a water-tight continuous trough of such character that there Will be no exposed place where ants can pass from the legs to the upper structure when the trough contains water. The intervening Q i r 7 1,576,358

portions of the trough provide for the curtains which also extend into the corner portions.

Having thus described the invention, I claim: r

In a device of the class described, a casing including legs, a frame and outer perforated walls, inner walls of textile material, a water tank in the upper portion of the casing, a trough surrounding the lower portion of the casing, the textilematerial extending into the upper tank and into the trough, said trough comprising a structure including a rectangular enlarged portion at each corner, a sleeve projecting upwardly from the center of each rectangular portion and adapted to surround the leg at that point, and narrow channels communicating with the rectangular portlons, adapted to receive the lower edge of the textile material, and permit-ting of the flow of fluid entirely 7 around each leg and the sleeve therefor, and from one of said enlarged rectangular portionsto the remainder of said JOHN S. PIHLSTROM.
